HOT-Al R DEFLECTO R.

SPECIFICATION forming part of Letters Patent No. 554,909, dated February18, 1896.

I Application filed November 1,1895, Serial No. 56 7,568. (No modeL) Toall whom it may concern.-

Be it known that I, SAMUEL S. CLARK, a citizen of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented a certain new and useful Improvement in Hot-Air Deflectors, ofwhich the following is a specification.

My invention relates to the construction of hot-air deflectors forradiators, registers, 85c. and has for its objects the production of adeflector which shall possess all the properties of the ordinary bentsheet-iron deflectors, and combine therewith an open tank of water intowhich all dust arising with the heated air on the under side of thedeflector will lodge.

To the aforesaid objects my invention consists in the peculiar and novelconstruction, combination, and arrangement of the various partshereinafter described,and then specifically claimed, reference being hadto the accompanying drawings, forming a part of this specification.

In the accompanying drawings, in which similar reference-numeralsindicate like parts in both views, Figure 1 is a perspective view withthe nearer side removed to better illustrate the interior construction,and Fig. 2 a perspective of a complete deflector.

In the drawings, 1 is a wide piece of thin sheet metal bent in an involute curve, one end terminating in a sharp inturned curve of much lessradius than the remaining portion thereof. This small curved portion isturned under and then up again, so as to nearly meet the concave side ofthe larger curve. 7

Each end is covered by side plates 2 and 3 of the same or stiffer metal,and are so cut as to conform generally to the configuration justdescribed for the curved side 1. On the inner or side placed away fromthe walls of the building (the radiators or registers being usuallyplaced close to the walls of the room) is a strap of metal 4, serving tohold the sides 2 and 3 firmly in place; but this is not absolutelynecessary.

The inturned portion of plate 1 I fill with water, and it is expectedthat this will be kept filled at all times, and in order to determinewhether it contains the required amount of water and also to furnish aneasy method of filling the same I place on the outside of one of plates2 or 3 a cup-shaped pocket 5, the side plate having an opening 6 nearthe bottom of this pocket to permit the water poured into it an entranceinto the tank formed by the curved top, and also to serve as anindicator of the amount of water in it. The hot air arisin g from theregister coming up through the open bottom of the deflector strikes itsconcave portion and passes along its surface around over the water anddown and out its open side into the room, and during its passage theparticles of dust reaching the highest portion of the concave part areprecipitated into the water, there to remain until removed. The waterbeing kept warm rapidly evaporates, and keeps the air in the room moist,preventing the extreme dryness incident to the use of hot-air furnaces.

What I claim is 1. A deflector for hot air consisting of a pair ofvertical side plates and a curved portion forming one side and top, saidcurved portion being bent downwardly to nearly form a circle, formingwith said sides a tank for water, substantially as shown and described.

2. A deflector for hot air, consisting of an involute curved portionending at the top in a sharp inturned part forming a tank with thesides,a pair of vertical side plates,and a pocket on one of said sideplates connected by an orifice with said tank portion, substantially asshown and described.

.In' testimony that I claim the above I hereunto set my hand.

SAMUEL S. CLARK.
